This disposable diaper can be worn as an open-type diaper after separating the front and back bodies with the cutting line by providing the cutting line and the fastening piece as described above.
JP-A-5-317356

上記締結片は、切断線で前後身頃が切り離されるまで使用されないが、締結片がおむつの外面側に位置しているため、使用前に、いたずら等によって係着部が汚されて締結片が使用できなくなったり、締結片の係着部が着用者の肌に触れて着用者が不快感を覚えたりする虞があった。   The fastening piece is not used until the front and back bodies are separated by a cutting line, but since the fastening piece is located on the outer surface side of the diaper, the fastening piece is used because the engaging part is soiled by mischief etc. before use There is a possibility that the wearer may not be able to do so, or the engaging portion of the fastening piece may touch the skin of the wearer and the wearer may feel uncomfortable.

この発明は、上述のような課題に鑑みてなされたものであり、接合されている前後身頃を切り離した後にそれらを再び連結する締結手段を備え、その締結手段を使用時まで汚すことがなく、かつ着用者の肌に触れることがない状態に保つことができる使い捨て着用物品を提供することを目的とする。   This invention has been made in view of the problems as described above, and includes fastening means for reconnecting them after separating the front and back bodies that have been joined, without contaminating the fastening means until use, And it aims at providing the disposable wearing article which can be maintained in the state which does not touch a wearer's skin.

上記課題を解決するためのこの発明に係る使い捨て着用物品は、長さ方向，幅方向，内面，外面，互いに対向し胴周域を有する第１パネル部および第２パネル部を有し、前記第１パネル部と前記第２パネル部とがそれらの幅方向胴周両側部で連結されているパンツ型の使い捨て着用物品において、前記第１および第２パネルの幅方向両側部の少なくとも一方の前記第１および第２パネルの側部は、前記第１および第２パネルの前記側部の間を跨ぎ前記側部の内面に接合された引き裂き可能な連結片を介して連結され、前記第１および第２パネルの前記側部の間における前記連結片の部位に、引き裂いて前記第１パネル部と前記第２パネル部とを互いに切り離すことが可能な切断部が設けられており、切り離された前記第１パネル部を前記第２パネル部と再び連結させることが可能な締結部材が、前記切断部に近接する部位の前記連結片の内面に接合されており、前記切断部を含む前記連結片と前記締結部材とを覆う、引き裂き可能な被覆部材が、前記切断部および前記締結部材を除いて、前記連結片の両側部の内面に接合されており、前記連結片および前記被覆部材が引き裂かれることにより、前記第１パネル部と前記第２パネル部とが切り離され、前記被覆部材が捲れて前記締結部材が露出するように構成されていることを特徴とする。 Disposable wearing article according to the present invention for solving the above problems has a length direction, a width direction, an inner surface, an outer surface, a first panel portion and the second panel section having mutually opposing cylinder peripheral region, the second in the first panel portion and the second panel portion is disposable wearing article pants-type that are connected at their widthwise girth sides, at least one of the width direction both side portions of the first and second panel second The side portions of the first and second panels are connected via a tearable connecting piece that spans between the side portions of the first and second panels and is joined to the inner surface of the side portion. A cutting portion that can be torn apart from the first panel portion and the second panel portion is provided at a portion of the connecting piece between the side portions of the two panels . 1 panel part is the second Fastening member capable of connecting channel portion and again, said portion adjacent to the cutting portion is bonded to the inner surface of the coupling piece, covers said fastening member and the connecting piece including the cutting portion, the tear Possible covering members are joined to the inner surfaces of both side portions of the connecting piece except for the cutting portion and the fastening member, and the connecting piece and the covering member are torn , whereby the first panel portion and The second panel portion is separated, and the covering member is rolled to expose the fastening member.

このように、締結部材が物品の内面側に設けられ、なおかつ被覆部材によって覆われていることにより、締結部材がいたずら等によって汚されて使用不可能な状態になったり、締結片の係着部が着用者の肌に触れて着用者が不快感を覚えたりすることを防止できる。被覆部材が、切断部と締結部材とを覆っていることにより、第１パネル部と第２パネル部とを切り離そうとする力が切断部に加えられたときに、その力が被覆部材にも伝わり、その結果、被覆部材が捲れて、隠れていた締結部材が露出する。第１パネル部と第２パネル部とが切り離された後、露出した締結部材を用いて第１パネル部と第２パネル部とを再び連結すれば、この着用物品を開放型として使用することができる。   As described above, the fastening member is provided on the inner surface side of the article and is covered with the covering member, so that the fastening member is soiled by mischief or the like and becomes unusable, or the engaging portion of the fastening piece. Can prevent the wearer from feeling uncomfortable by touching the skin of the wearer. Since the covering member covers the cutting portion and the fastening member, when a force for separating the first panel portion and the second panel portion is applied to the cutting portion, the force is applied to the covering member. As a result, the covering member is rolled, and the fastening member that has been hidden is exposed. If the first panel portion and the second panel portion are connected again using the exposed fastening member after the first panel portion and the second panel portion are cut off, the worn article can be used as an open mold. it can.

第１パネル部と第２パネル部とは、どちらが前側でどちらが後ろ側でもよいが、締結部材が設けられている第１パネル部が後ろ側であることが好ましい。そうすると、この着用物品を開放型として使用するときに、着用者を仰向けに寝かせたままの状態で、前側である第２パネル部の外面に後ろ側である第１パネル部を重ね合わせてそれらのパネル部を再び連結することが容易になる。   The first panel part and the second panel part may be either the front side or the rear side, but the first panel part provided with the fastening member is preferably the rear side. Then, when using this wearing article as an open mold, with the wearer lying on his back, the first panel portion on the rear side is superimposed on the outer surface of the second panel portion on the front side, It becomes easy to connect the panel portions again.

第１パネル部と第２パネル部とは、互いに対向する幅方向胴周両側部で直接連結されていてもよく、間接的に連結されていてもよい。ここで、第１パネル部と第２パネル部とが直接的に連結されているとは、第１パネル部と第２パネル部とが、互いに重なり合う部分において、接着あるいは溶着している状態である。一方、第１パネル部と第２パネル部とが間接的に連結されているとは、第１パネル部と第２パネル部との間に、物品本体を構成する部材とは別の部材が介在し、第１パネル部および第２パネル部の各々が、その別の部材と接着あるいは溶着している状態である。このように第１パネル部と第２パネル部とを連結する部材を、以下、連結片という。連結片は、物品の内面および外面のどちらか一方に接合されてもよく、内面および外面の両面に接合されてもよい。   The 1st panel part and the 2nd panel part may be directly connected with the width direction trunk circumference both sides which counter mutually, and may be connected indirectly. Here, the first panel portion and the second panel portion being directly connected is a state in which the first panel portion and the second panel portion are bonded or welded to each other at an overlapping portion. . On the other hand, the fact that the first panel portion and the second panel portion are indirectly connected means that a member different from the member constituting the article body is interposed between the first panel portion and the second panel portion. In addition, each of the first panel portion and the second panel portion is in a state of being bonded or welded to the other member. The member that connects the first panel portion and the second panel portion in this manner is hereinafter referred to as a connecting piece. The connecting piece may be bonded to either the inner surface or the outer surface of the article, or may be bonded to both the inner surface and the outer surface.

切断部は、第１パネル部と第２パネル部とが連結されている胴周両側部の少なくとも一方に設けられていればよいが、胴周両側部の両方に設けられていると、物品の着脱が容易になってより好ましい。
胴周側部とは、第１パネル部と第２パネル部との境界およびその周辺一帯である。切断部は、胴周側部であれば、境界以外の部分にあってもよいが、切断部が第１パネル部と第２パネル部との境界にあると、そこで第１パネル部と第２パネル部とを切り離し易くなってより好ましい。例えば、第１パネル部と第２パネル部とが直接連結されていて、切断部がそれらパネル部の境界である場合には、第１パネル部と第２パネル部との接合強度を調節することによって、第１パネル部と第２パネル部とを切り離し易くすることができる。また、第１パネル部と第２パネル部とが連結片を介して間接的に連結されていて、切断部が、それらパネル部の境界である連結片である場合には、連結片を物品のその他の部分と比べて破れ易い、あるいは引き裂かれ易い部分とすることによって、第１パネル部と第２パネル部とを切り離し易くすることができる。切断部は、そこで第１パネル部と第２パネル部とを切り離すことができる限りにおいては、その形成材料や形状について特に限定されるものではないが、切断部が、物品のその他の部分と比べて破れ易い、あるいは引き裂かれ易い部分であることが好ましい。例えば、切断部は、物品の長さ方向に直線的、かつ断続的に設けられたスリット、すなわち所謂ミシン線でもよく、物品の長さ方向の端部において引き裂き開始点となるように設けられた切り込みでもよい。また、物品が上述のような連結片を含む場合には、連結片を、物品のその他の部分よりも破れ易い、あるいは引き裂かれ易い性質を有するシート材料で形成し、それを切断部としてもよい。連結片を切断部として、そこで第１パネル部と第２パネル部とを切り離す場合には、物品が、吸収体を構成するパルプや高吸収性ポリマー粒子などの内容物を内部に含んでいても、第１パネル部と第２パネル部とを切り離したときにそれらの内容物が外部へ飛び出す心配がない。 The cutting portion only needs to be provided on at least one of the both sides of the waist circumference where the first panel portion and the second panel portion are connected. It is more preferable because it can be easily attached and detached.
The trunk side portion is the boundary between the first panel portion and the second panel portion and the surrounding area. The cutting part may be in a portion other than the boundary as long as it is a trunk peripheral side part. It is more preferable because it is easy to separate the panel portion. For example, when the first panel part and the second panel part are directly connected and the cutting part is a boundary between the panel parts, the bonding strength between the first panel part and the second panel part is adjusted. Therefore, it is possible to easily separate the first panel portion and the second panel portion. Moreover, when the 1st panel part and the 2nd panel part are indirectly connected via the connection piece, and a cutting | disconnection part is a connection piece which is a boundary of these panel parts, a connection piece is used for an article. The first panel portion and the second panel portion can be easily separated from each other by making the portion more easily torn or torn than the other portions. The cutting portion is not particularly limited as to the material and shape of the cut as long as the first panel portion and the second panel portion can be separated there, but the cutting portion is compared with other portions of the article. It is preferable that the portion be easily torn or torn easily. For example, the cutting portion may be a slit provided linearly and intermittently in the length direction of the article, that is, a so-called sewing line, and is provided so as to be a tear start point at an end portion in the length direction of the article. A notch may be used. When the article includes a connecting piece as described above, the connecting piece may be formed of a sheet material that is more easily torn or torn than other parts of the article, and may be used as a cutting portion. . When the connecting piece is a cutting part and the first panel part and the second panel part are separated there, the article may contain contents such as pulp and superabsorbent polymer particles constituting the absorber. When the first panel portion and the second panel portion are separated from each other, there is no concern that their contents will jump out.

締結部材を覆う被覆部材が、第１パネル部の内面側に設けられていて、物品の内面と被覆部材との間に締結部材が介在しているとき、被覆部材は、切断部および締結部材に重なる部分で、それらに粘着剤あるいはメカニカルファスナ等の接合手段によって剥離可能に接合されていてもよい。しかしながら、第１パネル部と第２パネル部との切り離し時に被覆部材が無理なく捲れるためには、被覆部材が、切断部および締結部材と重なる部分でそれらに接合されていないことが好ましい。その場合、被覆部材は、第１パネル部の内面側に確実に固定されるように、その幅方向の両側部で第１パネル部の内面側に接合されていることが好ましい。   When the covering member covering the fastening member is provided on the inner surface side of the first panel portion and the fastening member is interposed between the inner surface of the article and the covering member, the covering member is attached to the cutting portion and the fastening member. The overlapping portions may be detachably bonded to each other by a bonding means such as an adhesive or a mechanical fastener. However, it is preferable that the covering member is not joined to the cut portion and the fastening member so that the covering member can be rolled easily when the first panel portion and the second panel portion are separated. In that case, it is preferable that the covering member is joined to the inner surface side of the first panel portion at both side portions in the width direction so as to be securely fixed to the inner surface side of the first panel portion.

さらに、第１パネル部と第２パネル部との切り離し時に、被覆部材がより捲れ易くなるように、被覆部材を長さ方向に裂け易いシート材料で形成したり、被覆部材に長さ方向に裂け易い部分を設けたりすると好ましい。被覆部材に、長さ方向に裂け易い部分を設ける場合には、その裂け易い部分が、締結部材の幅方向の両側部のうち、切断部が近接する側部とは反対の側部に近接していることがより好ましい。そのような位置に裂け易い部分が設けられていると、裂け易い部分で被覆部材が破れると同時に、締結部材の締結面を広範囲にわたって露出させることができる。それによって、第１パネル部と第２パネル部とを切り離す作業とは別に被覆部材を捲って締結部材を露出させる作業を行う必要がないうえ、締結部材の締結面を有効利用することができる。裂け易い部分は、被覆部材において長さ方向に設けられた切り込み線、即ちスリットとすることができる。スリットは、１本でもよいが、複数本であることが好ましい。スリットが複数本ある場合には、被覆部材の上端から下端まで延びる所謂ミシン線として設けられていると、より好ましい。   Furthermore, when the first panel portion and the second panel portion are separated from each other, the covering member is formed of a sheet material that can be easily torn in the length direction so that the covering member can be more easily rolled, or the covering member is torn in the length direction. It is preferable to provide an easy part. In the case where the covering member is provided with a portion that is easily torn in the length direction, the easily torn portion is adjacent to a side portion opposite to the side portion to which the cutting portion is adjacent, of both side portions in the width direction of the fastening member. More preferably. If a portion that is easy to tear is provided at such a position, the covering member is torn at the portion that is easy to tear, and at the same time, the fastening surface of the fastening member can be exposed over a wide range. Thereby, it is not necessary to perform the operation of exposing the fastening member by covering the covering member separately from the operation of separating the first panel portion and the second panel portion, and the fastening surface of the fastening member can be effectively used. The easily tearable portion can be a cut line provided in the length direction in the covering member, that is, a slit. One slit may be used, but a plurality of slits are preferable. When there are a plurality of slits, it is more preferable that the slit is provided as a so-called sewing line extending from the upper end to the lower end of the covering member.

この発明において、切り離す、引き裂く、あるいは破るといったときには、人が素手で行い得る動作を意味するものとする。   In the present invention, when separating, tearing, or tearing, it means an action that a person can perform with bare hands.

この発明に係る使い捨て着用物品によれば、締結部材がシャーシの内面側に設けられていて、締結部材の全面が被覆部材で覆われているから、切断部で前後パネル部を切り離すまで、締結部材を使用時まで汚すことがなく、かつ着用者の肌に触れることがない状態に保つことができる。   According to the disposable wearing article according to the present invention, the fastening member is provided on the inner surface side of the chassis, and the entire surface of the fastening member is covered with the covering member. Can be kept in a state that does not get dirty until it is used and does not touch the skin of the wearer.

The connecting piece 20 is joined to the inner surface 14 by an adhesive 30 so as to straddle the front panel portion 16 and the rear panel portion 17 (see FIGS. 2 and 3).

使い捨ておむつ１０の胴周両側部１８，１９には、前パネル部１６と後パネル部１７とを切り離すことが可能な一対の切断部２２が設けられている。より詳しくは、切断部２２は、外側へ延出する両耳部１８ａ，１８ａの間および両耳部１９ａ，１９ａの間における連結片２０上の、前パネル部１６と後パネル部１７との境界２１にある（図２を参照）。切断部２２は、胴周両側部１８，１９のどちらか一方に設けられていてもよいが、図示されているように、胴周両側部１８，１９の両方に切断部２２が設けられていると、切断部２２で連結片２０を手で引き裂いて前パネル部１６と後パネル部１７とを切り離すことによって、使い捨ておむつ１０を完全に展開することができ、使い捨ておむつ１０の着脱の操作が容易になる。   A pair of cutting portions 22 capable of separating the front panel portion 16 and the rear panel portion 17 are provided on both sides 18 and 19 of the waist circumference of the disposable diaper 10. More specifically, the cutting portion 22 is a boundary between the front panel portion 16 and the rear panel portion 17 on the connecting piece 20 between the both ear portions 18a and 18a extending outward and between the both ear portions 19a and 19a. 21 (see FIG. 2). The cutting portion 22 may be provided on either one of the waist circumference side portions 18 and 19, but as shown in the drawing, the cutting portion 22 is provided on both the waist circumference side portions 18 and 19. Then, by tearing the connecting piece 20 by the cutting part 22 by hand and separating the front panel part 16 and the rear panel part 17, the disposable diaper 10 can be fully developed, and the operation of attaching and detaching the disposable diaper 10 is easy. become.

胴周弾性部材４１および脚周弾性部材４３が、それぞれ、公知の手段によって胴開口および脚開口に沿って取り付けられている。さらに、前後パネル部１６，１７の胴周弾性部材４１より下側には、胴周および脚周弾性部材４１，４３の伸長応力よりも低い伸長応力を有し、幅方向に延びる胴周補助弾性部材４２が取り付けられている。胴周弾性部材４１，胴周補助弾性部材４２および脚周弾性部材４３は、表面シート１１および裏面シート１２の間に挟まれており、表裏面シート１１，１２の少なくともどちらか一方に、伸長状態下に接着剤（図示せず）によって接合されている。
胴周弾性部材４１および胴周補助弾性部材４２は、前パネル部１６に配置されている前半分と後パネル部１７に配置されている後半分とに分かれており、それら前半分と後半分とは胴周両側部１８，１９で連続していない。すなわち、胴周弾性部材４１は、切断部２２である前パネル部１６と後パネル部１７との境界２１には存在していない。
脚周弾性部材４３は、脚開口周縁の上半分に配置されている。脚周弾性部材４３も、胴周弾性部材４１と同様に、前パネル部１６に配置されている前半分と後パネル部１７に配置されている後半分とに分けられ、それら前半分と後半分とは胴周両側部１８，１９で連続していない。すなわち、脚周弾性部材４３は、切断部２２である前パネル部１６と後パネル部１７との境界２１には存在していない。
このように、切断部２２に、いずれの弾性部材４１，４２，４３も存在していないことによって、切断部２２において前後パネル部１６，１７を切り離すことが容易であり、また、前後パネル部１６，１７の切り離し時に弾性部材が切れて手に当たるという煩わしさを感じることがなく、好ましい。 The waist circumference elastic member 41 and the leg circumference elastic member 43 are respectively attached along the waist opening and the leg opening by known means. Further, below the waist circumference elastic member 41 of the front and rear panel portions 16 and 17, the waist circumference auxiliary elasticity has an extension stress lower than the extension stress of the waist circumference and leg circumference elastic members 41 and 43 and extends in the width direction. A member 42 is attached. The waist circumference elastic member 41, the waist circumference auxiliary elastic member 42, and the leg circumference elastic member 43 are sandwiched between the top sheet 11 and the back sheet 12, and are stretched between at least one of the front and back sheets 11, 12. It is joined below by an adhesive (not shown).
The waist circumference elastic member 41 and the waist circumference auxiliary elastic member 42 are divided into a front half disposed in the front panel portion 16 and a rear half disposed in the rear panel portion 17. Is not continuous on both sides 18 and 19 of the waist. That is, the waist circumference elastic member 41 does not exist at the boundary 21 between the front panel portion 16 and the rear panel portion 17 which are the cut portions 22.
The leg circumference elastic member 43 is disposed in the upper half of the leg opening periphery. Similarly to the waist elastic member 41, the leg elastic member 43 is divided into a front half arranged in the front panel portion 16 and a rear half arranged in the rear panel portion 17, and the front half and the rear half are divided. Is not continuous on both sides 18 and 19 of the waist. That is, the leg circumferential elastic member 43 does not exist at the boundary 21 between the front panel portion 16 and the rear panel portion 17 which are the cutting portions 22.
Thus, since none of the elastic members 41, 42, 43 is present in the cutting part 22, it is easy to separate the front and rear panel parts 16, 17 at the cutting part 22, and the front / rear panel part 16 , 17 is preferable because it does not feel annoying that the elastic member breaks and hits the hand when it is cut off.

切り離された前パネル部１６と後パネル部１７とを再び連結することが可能であって、連結片２０の剛性よりも高い剛性を有する一対の締結部材２３，２３が、胴周両側部１８，１９における切断部２２に近接するように後パネル部１７の内面１４側に設けられている。締結部材２３は、図２および３に示されているように、後パネル部１７の側縁に沿って位置するように設けられていることが好ましい。締結部材２３がこのように設けられていると、締結部材２３の側縁に沿って連結片２０を引き裂くことができ、前パネル部１６と後パネル部１７との切り離しが容易になる。
締結部材２３は、接着剤３１によって連結片２０に接合されている。この接着剤３１は、図示の使い捨ておむつ１０において、締結部材２３の、連結片２０との接合面全体に塗布されているが、使い捨ておむつ１０の使用上十分な接合強度が得られる限りにおいては、締結部材２３の、連結片２０との接合面に部分的に塗布されていてもよい。ただし、接着剤３１が、締結部材２３の、連結片２０との接合面に部分的に塗布される場合には、締結部材２３の幅方向Ｗの両側部２３ａ，２３ｂのうち、少なくとも側部２３ｂに接着剤３１が塗布されていることが好ましい。前後パネル部１６，１７を切り離した後、締結部材２３を介して前後パネル部１６，１７を再び連結して、使い捨ておむつ１０を開放型として使用するときに、締結部材２３が前パネル部１６寄りに位置する側部２３ａで接着剤３１によって後パネル部１７の内面１４側に接合されている場合には、締結部材２３にせん断力が作用すると前後パネル部１６，１７が離れ易い。これに対して、締結部材２３が側部２３ｂで接着剤３１によって後パネル部１７の内面１４側に接合されている場合には、前述の場合と接着剤３１の塗布面積が同じであっても、前述の場合と比較して、前後パネル部１６，１７が離れ難い。
図示されている締結部材２３は、メカニカルファスナのフック部材であるが、締結部材２３として、表面に粘着剤が塗布された粘着テープを用いてもよい。その場合には、被覆部材２４として離型性を有するシート片を用いるか、あるいはシート片の、締結部材２３との接触面に離型剤を塗布する等の離型処理を施して、シート片を締結部材２３の表面から捲れ易くすることが好ましい。 The pair of fastening members 23, 23 capable of reconnecting the separated front panel portion 16 and rear panel portion 17 and having a rigidity higher than the rigidity of the connecting piece 20 are provided on both side portions 18, 18. 19 is provided on the inner surface 14 side of the rear panel portion 17 so as to be close to the cutting portion 22. The fastening member 23 is preferably provided so as to be positioned along the side edge of the rear panel portion 17 as shown in FIGS. When the fastening member 23 is provided in this way, the connecting piece 20 can be torn along the side edge of the fastening member 23, and the front panel portion 16 and the rear panel portion 17 can be easily separated.
The fastening member 23 is joined to the connecting piece 20 by an adhesive 31. In the illustrated disposable diaper 10, the adhesive 31 is applied to the entire joining surface of the fastening member 23 with the connecting piece 20, but as long as sufficient bonding strength is obtained for use of the disposable diaper 10, The fastening member 23 may be partially applied to the joint surface with the connecting piece 20. However, when the adhesive 31 is partially applied to the joint surface of the fastening member 23 with the connecting piece 20, at least the side portion 23 b of the side portions 23 a and 23 b in the width direction W of the fastening member 23. It is preferable that the adhesive 31 is applied. After separating the front and rear panel portions 16 and 17, the front and rear panel portions 16 and 17 are connected again via the fastening member 23, and when the disposable diaper 10 is used as an open mold, the fastening member 23 is closer to the front panel portion 16. In the case where the side portion 23a located at the side is joined to the inner surface 14 side of the rear panel portion 17 by the adhesive 31, the front and rear panel portions 16 and 17 are easily separated when a shearing force acts on the fastening member 23. On the other hand, when the fastening member 23 is joined to the inner surface 14 side of the rear panel portion 17 by the adhesive 31 at the side portion 23b, the application area of the adhesive 31 is the same as that described above. Compared with the above-described case, the front and rear panel portions 16 and 17 are less likely to be separated.
Although the illustrated fastening member 23 is a hook member of a mechanical fastener, an adhesive tape having a surface coated with an adhesive may be used as the fastening member 23. In that case, a sheet piece having releasability is used as the covering member 24, or the sheet piece is subjected to a release treatment such as applying a release agent to the contact surface of the sheet piece with the fastening member 23. It is preferable to make it easy to bend from the surface of the fastening member 23.

締結部材２３は、被覆部材２４によって覆われている。この被覆部材２４は、切断部２２と締結部材２３とを覆って、後パネル部１７の内面１４の側に設けられている（図３を参照）。被覆部材２４は、幅方向Ｗの両側部２４ａ，２４ｂで、接着剤３２によって連結片２０に接合されているが、切断部２２および締結部材２３に重なる部分２４ｃでは、それらに接合されていない。このように、被覆部材２４が、切断部２２と締結部材２３とに対して接合されていない状態にあると、切断部２２に作用する引き裂き力が被覆部材２４の他の部分に伝わり易いとともに、締結部材２３の表面から被覆部材２４を剥離させるための力を必要としないから、前パネル部１６と後パネル部１７とを極めて容易に手で切り離すことができる。また、連結片２０と締結部材２３と被覆部材２４とが、図示のように重ね合わされて接合される場合には、連結片２０と締結部材２３と被覆部材２４とをひとつのユニットとして予め準備しておくことにより、それらの部材をこの使い捨ておむつ１０に取り付けることが容易になる。   The fastening member 23 is covered with a covering member 24. The covering member 24 covers the cutting part 22 and the fastening member 23 and is provided on the inner surface 14 side of the rear panel part 17 (see FIG. 3). The covering member 24 is joined to the connecting piece 20 by the adhesive 32 at both side portions 24a and 24b in the width direction W, but is not joined to the portion 24c overlapping the cutting portion 22 and the fastening member 23. As described above, when the covering member 24 is not joined to the cutting portion 22 and the fastening member 23, the tearing force acting on the cutting portion 22 is easily transmitted to other portions of the covering member 24, and Since the force for peeling off the covering member 24 from the surface of the fastening member 23 is not required, the front panel portion 16 and the rear panel portion 17 can be separated very easily by hand. When the connecting piece 20, the fastening member 23, and the covering member 24 are overlapped and joined as illustrated, the connecting piece 20, the fastening member 23, and the covering member 24 are prepared in advance as one unit. It becomes easy to attach those members to this disposable diaper 10 by keeping.

図４は、使い捨ておむつ１０の内面１４の側からみた胴周側部１８の拡大図である。ただし、便宜上、被覆部材２４が部分的に破断されて示されている。図５は、使い捨ておむつ１０の外面１５の側からみた胴周側部１８の拡大図である。図６は、前パネル部１６と後パネル部１７とが切断部２２で切り離された後の胴周側部１８を示す図４相当図である。
図４に示されているように、胴周側部１８で、切断部２２および締結部材２３を覆う被覆部材２４には、長さ方向Ｌに裂け易い部分２５が設けられている。裂け易い部分２５は、例えば、長さ方向Ｌに設けられたスリットとすることができ、図４に示されているように、被覆部材２４の上端から下端まで延びるミシン線であるとより好ましい。図４に示されている裂け易い部分２５は、締結部材２３の幅方向Ｗの両側部２３ａ，２３ｂのうち、切断部２２が近接する側部２３ａと反対側の側部２３ｂに近接して、締結部材２３上に位置しているが、締結部材２３の縁に沿って、あるいは締結部材２３の縁より外側にあって側部２３ｂに近接していてもよい（図示せず）。裂け易い部分２５が締結部材２３の縁より外側にある場合には、被覆部材２４が裂け易い部分２５で破れて捲れたときに、締結部材２３が幅方向Ｗの全長にわたって露出する。それによって、締結部材２３の締結面を有効に利用することができる。 FIG. 4 is an enlarged view of the trunk circumferential side portion 18 viewed from the inner surface 14 side of the disposable diaper 10. However, for convenience, the covering member 24 is shown partially broken. FIG. 5 is an enlarged view of the trunk circumferential side portion 18 viewed from the outer surface 15 side of the disposable diaper 10. FIG. 6 is a view corresponding to FIG. 4 showing the trunk peripheral side portion 18 after the front panel portion 16 and the rear panel portion 17 are separated by the cutting portion 22.
As shown in FIG. 4, the covering member 24 that covers the cutting portion 22 and the fastening member 23 at the body circumferential side portion 18 is provided with a portion 25 that is easily torn in the length direction L. The easy-to-break portion 25 can be, for example, a slit provided in the length direction L, and is more preferably a sewing line extending from the upper end to the lower end of the covering member 24 as shown in FIG. The portion 25 that is easily torn shown in FIG. 4 is close to the side portion 23b opposite to the side portion 23a that the cutting portion 22 is close to, of the both side portions 23a and 23b in the width direction W of the fastening member 23. Although it is located on the fastening member 23, it may be along the edge of the fastening member 23 or outside the edge of the fastening member 23 and close to the side portion 23b (not shown). In the case where the easily tearable portion 25 is outside the edge of the fastening member 23 , the fastening member 23 is exposed over the entire length in the width direction W when the covering member 24 is torn at the easily tearable portion 25. Thereby, the fastening surface of the fastening member 23 can be used effectively.

前パネル部１６と後パネル部１７とを切り離すときには、胴周側部１８および／または胴周側部１９で、切断部２２の幅方向Ｗ両側を両手で摘み、連結片２０を長さ方向Ｌに引き裂くように力を加える。この力は、内面側で連結片２０に重なっている被覆部材２４にも伝わる。被覆部材２４は、はじめに切断部２２で連結片２０とともに引き裂かれるが、やがては引き裂き容易な部位２５で破れる（図６を参照）。被覆部材２４が引き裂き容易な部位２５で破れるときには、その他の部位で破れるときよりも弱い力で容易に破れるから、切断部２２が被覆部材２４によって覆われていても、前パネル部１６と後パネル部１７とを容易に切り離すことができる。   When the front panel portion 16 and the rear panel portion 17 are separated from each other, the both sides of the cutting portion 22 in the width direction W are picked with both hands at the trunk peripheral side portion 18 and / or the trunk peripheral side portion 19, and the connecting piece 20 is lengthwise L Apply force to tear. This force is also transmitted to the covering member 24 that overlaps the connecting piece 20 on the inner surface side. The covering member 24 is first torn together with the connecting piece 20 at the cutting portion 22, but eventually is torn at a portion 25 that is easily torn (see FIG. 6). When the covering member 24 is torn at the easily tearable portion 25, it is easily torn with a weaker force than when it is torn at other portions. The part 17 can be easily separated.

上述のような構成を備える使い捨ておむつ１０は、前パネル部１６と後パネル部１７とが切り離されると同時に被覆部材２４が捲れて締結部材２３が露出する。   In the disposable diaper 10 having the above-described configuration, the covering member 24 is rolled and the fastening member 23 is exposed at the same time as the front panel portion 16 and the rear panel portion 17 are separated.

前パネル部１６および後パネル部１７は、連結片２０を介さずに、直接連結されてもよい。連結片２０が省略される場合、前後パネル部１６，１７は、手で切り離すことができる程度の接合強度を有するように公知の手段によって直接接合される。このとき、締結片２０および被覆部材２４は、後パネル部１７（または前パネル部１６）に直接接合される。前パネル部１６および後パネル部１７が直接連結されていても、使い捨ておむつ１０が上述のような構成の締結片２０および被覆部材２４を備えていることによって、前パネル部１６と後パネル部１７とが切り離されると同時に被覆部材２４が捲れて締結部材２３が露出する。   The front panel portion 16 and the rear panel portion 17 may be directly connected without using the connecting piece 20. When the connecting piece 20 is omitted, the front and rear panel portions 16 and 17 are directly joined by a known means so as to have a joining strength that can be separated by hand. At this time, the fastening piece 20 and the covering member 24 are directly joined to the rear panel portion 17 (or the front panel portion 16). Even if the front panel portion 16 and the rear panel portion 17 are directly connected, the front panel portion 16 and the rear panel portion 17 are provided by the disposable diaper 10 including the fastening piece 20 and the covering member 24 having the above-described configuration. At the same time, the covering member 24 is rolled and the fastening member 23 is exposed.
